    Abstract:
    This retrospective study describes various buccinator musculomucosal flaps for the repair of palatal fistulae. Twenty-two palatal fistulae were repaired at our institution between 2002 and 2012 by buccinator musculomucosal flaps with superior-anterior or posterior pedicles. Seventeen patients were treated with posteriorly pedicled flaps, 7 of whom had lengthening of the soft palate and 10 of whom had simultaneously repaired severe lateral palatal scarring. Five patients with anterior or midpalatal fistulae were treated with superior-anteriorly pedicled flaps. All but 4 of the 22 patients had satisfactory results. Four patients had recurrent fistulae, 2 resulting from flap tip necrosis and 2 from wound dehiscence. Follow-up was from 5 to 72 months. None of the patients had facial nerve injury, limited mouth opening, or difficulty chewing. We evaluated the factors that could cause complications, such as flap pattern, location of fistula, and size of palate defect. No statistically significant differences were found in the complication rates among different groups. In conclusion, the buccinator musculomucosal flap is reliable and versatile, with rich vascularity and flexible design. The flap is a good option for fistula repair, especially for larger fistulae at the anterior portion of the hard palate or at the junction of hard and soft palate, where surrounding soft tissues are stiff, scarred, and difficult to mobilize.
